In reply to howfantastic:
> Now, to my question, I have recently completed the Climbing Wall award, and want to know what this means to climbers. Should we just start with some light bouldering to get the muscles working, or perhaps some games?
Yes. Games are a great way to warm up, but low-level traversing and games involving climbing holds are very useful when time is short and the kids are itching to get onto the wall.
> Watching some of the full time ‘instructors’ at the walls I have visited all seem to focus on stretching – does this mean climbing is different?
No, it's not different. Stretching before warming up is no better for climbers than anyone else!
> Anybody else coach kids and know what the ‘recommended’ practice is?
IMHO, pretty well as you've suggested (ie games and gentle bouldering).
